TRUSS.

SPECIFICATION forming part of Letters Patent No. 731,709, dated. June23, 1 903 Application filed February 24, 1903. Serial 'No. 144,693.(No'modah) To all whom it may concern:

Be it known that I, JOHN RAILTON, a citizen of the United States,residing at Cheboygan, in the county of Gheboygan and State of Michigan,have invented certain new and useful Improvements in Trusses, of whichthe following is a specification, reference being hadtherein to theaccompanying drawings.

The invention relates generally to trusses for the treatment of variousforms of hernia; and it consists in the novel construction of thetruss-pad, which is so formed as to admit of the application .ofpressure at the precise point or points in the manner hereinafter setforth. I

The invention further consists in the peculiar arrangement andcombination of the various parts of the pad, as will be presentlydescribed, and illustrated in the drawings, in

which- Figure 1 is a top plan view. Fig. 2 is a vertical central sectionthrough the pad, and

"Fig. 3 is a bottom view thereof.

In construction the pad is preferably of oval configuration, andconsists, essentially,

. of an outer inclosing casing A and an inner pneumatic pad member B.The casing is preferably, but not necessarily, made of'yielding materialand has a circular opening a formed in its top and a central aperture 1)in its under face or side. Arranged within the casing is the pad memberpreviously referred to, which may be made of any suitable material andis adapted when inflated to protrude in the manner indicated in Fig. 2through the casing-aperture. As a matter of preference the inner memberis in the form of a rubber bag provided with a suitab e inflating-nozzleD, projecting through the opening a and covered in the usual manner by acap E.

F and G represent circular plates at the top of the casing and arranged,respectively,

within and upon the exterior thereof. These plates are centrallyapertured', as at c, to allow the inflating-nozzle to pass therethroughand are so proportioned as to overlap the marginal portion (1 of theouter cover.

H is an'oblong plate to which the usual band (not shown) that passesabout the body of the wearer is attached. This is mounted upon the upperplate G, and the several platesections are connected by suitabledevices, such as screws e, the marginal portion of the casing beingtightly clamped between the plates, as illustrated.

WhileI have shown a single aperture in the casing, it will be obviousthat a] plurality of openings may be formed in the under part thereof,so that the bag will protrude at several places, permitting itsapplication at a.6o number of distinct points where pressure isrequired.

By constructing the pad in such manner that only a part or certainportions thereof are employed to exert pressure it can be properly andmost accurately fitted to the wearer and is comfortable in use.

'What'I claim as my invention is- 1. A truss-pad, comprising an outerapertured casing, and an inner inflatable member contacting with themarginal portions of the casing about the aperture and having, uponinflation, a relatively small portion thereof protruding uninterruptedlythrough said aperture.

2. A truss-pad, comprising an outer inclos ing casing of yieldingmaterial,having an aperture formed in its under side, and an innerpneumatic bag adapted when inflated to protrude through thecasing-aperture.

3. A truss-pad, comprising an oblong inclosing casing formed of yieldingmaterial having an opening in its top and an aperture formed in itsunder face, a rubber bag within the casing adapted when inflated toprotrude through the casing-aperture, and an inflatingnozzle for the bagprojecting normally through the opening in the casing-top.

In testimony whereof I afiix my signature in presence of two witnesses.

- JOHN RAILTON.
